To all whom it may concern:

Be it known that I, ALFRED M. LANE, a citizen of the United States, and'a resident of the city of St. Louis and State of Missouri, have invented a new and useful Improvement in Metal \Veather Strips, of which the following is a specification.

This invention relates to metal weather strips particularly adapted for windows equipped with sliding sashes and has for its principal object to produce an eflicient weather strip of simple construction and compact design which can be readily applied to such windows without material alteration thereof. Other objects are to reduce the cost of manufacture, to facilitate assembly, and to obtain other advantages hereinafter appearing. The invention consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed.

In the accompanyin drawing, wherein like symbols refer to ike parts wherever they occur,

Fig. 1 is a fragmentary horizontal cross section through one side of a Window casing and the adjacent portion of a. lower'sash provided with a weather strip embodying my invention; and

Fig. 2 is a horizontal cross-section similar to Fig. 1 showing a weather strip of modified form.

Referring to Figs. land 2 of the drawing, a portion of the casing or jamb member 3 of an ordinary window frame is shown as arranged for a closure in the form of a sliding sash 4, the respective Walls of the vertical slideway for the sash being formed by a parting strip or bead 5 and a stop member or molding 6.

The weather strip shown in Fig. 1 comprises cooperating metal strips or members 7 and 8 mounted vertically on the jamb 3 and on the sash 4, respectively. The cooperating j amb or frame strip 7 is relatively flexible or resilient and is secured along one marginal portion to the jamb 3 of the window frame, as at 9, preferably under the stop member or molding 6. The flexible or resilient jamb strip 7 extends betweenthe opposing surfaces of the jamb 3 and sash 4 and has its opposite free marginal portion longitudinally doubled to form a double thickness of metal which is bent away from the adjacent jamb substantially at right From the angles to said body portion, as at 9' so as to overlap the opposite corner of said sash.

doubled free marginal portion of the jam strip is bentawa from the adjacent side face of the sash su stantially at right angles to said portion 9 to form an outstanding tongue or rib 10. The extreme free marginal portion of the frame stri is preferably extended beyond the doub ed portion 9 thereof to form the flange 11. This flange portion works loosely in a vertical groove 12 provided therefor between the adjacent face of the parting strip and the adjacent wall of the groove provided therefor in the jamb member of the window frame. 7

The cooperating sash strip 8 is relatively rigid and is secured along one margin to the side face of' the sash, as at 13. The

opposite margin of the sash strip is bent portion 9", the lon 'itudinally outwardly away from the side face of the sash and thence backwardly toward saidsash to form a U-shaped groove 14 4 adapted for cooperatlon ue porstrip which with the'bead or ton tion 10 of the flexible frame has a loose sliding fit therein. In the construction illustrated in Fi 2 the free marginal portion of the flexible jamb strip 7 is longitudinally doubled and is bent across the corner of the sash and thence outwardly away from the side of the sash and backwardly toward the same to form a groove 14. Theextreme free mar ginal portion of the sash strip is extended beyond the doubled portion thereof to form a flange portion 11 which works loosely in the groove 12 in the jamb member 3. The

rigid sash strip 8} is of angle section and has one flange secured to the side face of the sashadjacent to the longitudinallv doubled free marginal portion of the jamb strip. The other flange of the sash strip projects away from the side face of the sashand has a 'loose sliding fit in the groove portion 14 of the flexible frame strip 7.

The weather strips above described are strong, durable'and of simple construction and can be easily applied to various types of windows without any alteration of the frame or sash. In addition to this,the device has the further advantage. of being very easy to make and any broken or worn part may be quickly and easily replaced. Another important advantage thatv the-device is not only waterproof under normal conditions but that it remains waterproof against hard rains and driving w nd. Under such conditions, the force of the wind against the sash tends to force the two cooperating strips into closer engagement with each other and thus prevent storm Water from being forced through the crack between the sash and the frame.

Obviousl the invention is not linnted to use with t e articular window construction shown and described.

What I claim is: 1. The combination with a frame and a closure therefor, of a relatively flexible member disposed between said frame and the adjacent face of said closure and secured along one margin to said frame ad acent to one side of said closure and a relatively rigid member secured along one margin to the opposite side of said closure, the free marginal portions of said members being formed with cooperating ribbed and grooved portions located opposite the side face of said closure outside the general plane thereof.

2. The combination with a frame and a closure therefor, of a relatively flexible member disposed between said frame and the adjacent end face of said closure and secured along one margin to said frame adjacent to one side of said closure and having its opposite free margin longitudinally doubled and formed into a rib, and a-relatively rigid member secured along one margin to the opposite side of said closure and having its opposite marginal portion formed into a groove adapted to'receive the rib at the free margin of said flexible member, the rib portion of said flexible member and the groove portion of said rigid member being located opposite the side face of said closure outside of the general plane thereof.

3. The combination with a frame and a closure therefor, a relatively flexible member disposed between said frame and the adjacent face of said closure, said member being secured along one margin to said frame adjacent to one side of said closure and having a longitudinally doubled free marginal portion extending around the opposite side of said closure and terminating in an outstanding portion, and a relatively rigid member secured to said opposite side of said closure and having an outstanding free marginal portion slidably engaging the outstanding longitudinally doubled free marginal portion of said flexible strip beyond the general plane of said closure.

Signed at St. Louis, Missouri, this 14th day of May, 1923.

ALFRED M. LANE.
